Two months later it was impossible for Jenny to not know she was pregnant. Her bump was visible and--yes, the doctor confirmed she was having *three* babies. She damned her life: having sex and getting pregnant right away was bad enough, but getting triplets out of the deal was way worse.
Tim didn't mind. He'd used the program to adjust Jenny's sexual needs, so that the bigger she got, the more sex she wanted. Tim figured by the time she was ready to give birth, she'd likely want an orgasm every hour on the hour--something that was going to tax him to the max.
By the end of her second trimester Jenny wanted sex at least three times a day. The problem was with all the extra baby weight Jenny put on, about all she could do was lay on her back and let Tim fuck her. He wanted to try a lot more things, so he fired up the program and made a few changes.
First, he fixed it so for every three pounds of fat Jenny gained, it would turn into a pound of muscle. He also changed thirty pounds of existing fat into ten pounds of muscle and spread it around Jenny's frame. Finally, he made her a D cup so that when it came time to give birth and her milk came in, she'd be incredibly, naturally huge.
Jenny had no idea she'd been changed again. What she did notice was carrying around three babies wasn't as hard as before, and she was becoming a lot more adventurous sexually.
